Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, specifically to a rock wool sandwich panel with a reinforced structure. Background Technology
[0002] Rock wool sandwich panels are sandwich panels made from rock wool. They fully utilize the unique properties of rock wool core material, exhibiting significant effects in fire resistance, thermal insulation, sound absorption, and sound insulation. Therefore, rock wool sandwich panels are a commonly used wall panel in steel structure buildings. They not only have the advantages of being lightweight, inexpensive, aesthetically pleasing, and easy to install, but also possess good fire resistance and thermal insulation properties.
[0003] Currently, rock wool sandwich panels are mostly assembled using an interference fit method where the male groove is inserted into the female groove. However, this traditional structure has significant drawbacks. From a stability perspective, the mating area between the male and female grooves is a hollow structure, lacking support and becoming a weak point. Under external forces such as wind and vibration, stress concentration can easily cause deformation or loosening, affecting the overall stability and potentially leading to separation after long-term use. Furthermore, the groove walls are relatively thin (typically 0.3-1mm galvanized or color-coated steel sheets), making them susceptible to dents and twists due to improper construction or transportation collisions. This deformation compromises the interference fit precision, creating gaps after splicing. In rainy, snowy, or humid environments, rainwater seeps in, causing the rock wool core material to become damp, reducing its insulation and strength, and even leading to problems such as water seepage and mold growth in the walls. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a rock wool sandwich panel with a reinforced structure to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rock wool sandwich panel with a reinforced structure, comprising a shell and a rock wool board, wherein the rock wool board is disposed inside the shell; a connector is provided on one side of the shell, and a insertion groove is provided on the other side of the shell; the connector includes a set of plug portions, two sets of ramp portions and two sets of sealing grooves, and the plug portions, ramp portions and sealing grooves are arranged from left to right; the insertion groove includes a set of slot portions, two sets of elastic portions and two sets of sealing strips.
[0006] Furthermore, the interior of the outer shell is fixed with multiple sets of reinforcing plates by rivets, and the multiple sets of reinforcing plates are evenly arranged at equal intervals.
[0007] By adopting the above technical solution, multiple sets of equidistant reinforcing plates are fixed inside the shell with rivets. This is to disperse external forces through a uniformly distributed support structure, avoid excessive local stress that could cause the shell to deform, and at the same time enhance the overall structural rigidity and impact resistance of the sandwich panel.
[0008] Furthermore, the elastic part bends toward the slot part, and an elastic strip is provided at the bend.
[0009] By adopting the above technical solution, reasonable deformation space is provided for the plug to be inserted to ensure smooth assembly, and the elastic strip can enhance the rebound force to ensure tightness when locked with the inclined part, thereby improving the stability of the splicing.
[0010] Furthermore, the reinforcing plate is in the shape of an "I" and is made of polypropylene plastic material.
[0011] By adopting the above technical solutions, the mechanical properties of the "I" structure are used to disperse stress and enhance bending resistance. The lightweight and chemically resistant properties of polypropylene are also utilized to reduce the overall weight of the sandwich panel. As a non-metallic material with extremely low thermal conductivity, polypropylene can effectively block the heat transfer path between metal components, eliminate the thermal bridge effect, and further ensure the thermal insulation performance of the rock wool sandwich panel.
[0012] Furthermore, the plug portion is adapted to the slot portion.
[0013] By adopting the above technical solutions, precise alignment during splicing is ensured, and the contact area is increased through close fitting, thereby improving the structural strength and sealing of the splice.
[0014] Furthermore, both the elastic strip and the sealing strip are fixed to the elastic part by adhesive bonding.
[0015] By adopting the above technical solutions, it is ensured that the elastic strip maintains its locking effect during repeated deformation and that the sealing strip continues to perform its sealing function.
[0016] Furthermore, the elastic strip is made of natural rubber, and the sealing strip is made of EPDM rubber.
[0017] By adopting the above technical solutions, natural rubber has excellent elasticity and resilience, which can ensure that the elastic strip provides stable elasticity during the compression-reset process and ensure the locking effect; while EPDM rubber has better weather resistance, aging resistance and water resistance, which can enable the sealing strip to continue to play a sealing role in long-term exposure environment and effectively resist moisture penetration.
[0018] Furthermore, the elastic strip and the sealing groove are adapted to each other.
[0019] By adopting the above technical solution, the elastic strip can be precisely fitted into the sealing groove to form a tight filling. It can also fully fit the inner wall of the sealing groove by taking advantage of the deformation characteristics of the elastic strip, thereby enhancing the sealing pressure at the joint, further blocking the intrusion path of rainwater and moisture, and improving the overall sealing reliability.
[0020] Furthermore, the outer casing is made of galvanized steel sheet.
[0021] By adopting the above technical solution, the electrochemical protective effect of the zinc plating layer is used to improve the corrosion resistance of the casing, which can effectively resist environmental erosion such as humidity and rainwater, and extend the service life.
[0022] In summary, the present invention has the following main advantages: 1. This utility model, by comprising a plug portion, a slot portion, an elastic portion, an inclined portion, a sealing strip, and a sealing groove, allows for precise fitting of the plug portion into the slot portion of the other rock wool sandwich panel during assembly. The inclined portion guides the elastic portion to undergo controllable deformation during insertion, ensuring the plug portion smoothly enters the slot portion. Compared to the hollow fit of traditional male and female slots, this increases the physical contact area at the joint, significantly enhancing structural strength. Even under strong wind impacts, mechanical vibrations, or external forces during installation, this design provides robust structural integrity. Impact resistance effectively resists deformation, completely compensating for the weakness of traditional structures. When the plug is in place, the elastic part quickly resets and locks tightly onto one side of the inclined part, forming a firm automatic locking state. This locking method not only avoids the loosening problem that may occur in traditional splicing, but also greatly improves the stability of the assembly. At the same time, when the elastic part resets, it will drive the sealing strip to fit into the sealing groove perfectly. Compared with the natural fit of traditional splicing, this sealing method is more reliable and can completely block the intrusion path of rainwater and moisture, ensuring the thermal insulation performance of the rock wool sandwich panel. 2. This utility model features multiple sets of reinforcing plates in an "I" shape. The "I"-shaped structure, through the coordinated force distribution of the upper and lower flanges and the middle web, evenly distributes external forces across the entire panel surface, significantly improving the bending resistance of the sandwich panel. Even under significant external pressure (such as heavy pressure during installation, collisions during transportation, or structural stress during long-term use), it effectively resists deformation, completely solving the problem of traditional rock wool sandwich panels being prone to bending and deformation due to insufficient strength. This ensures the structural integrity of the sandwich panel while maintaining its flat appearance and stable performance over the long term, providing a more solid support for the safety of building envelope structures.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0026] The embodiments of this utility model will be described below based on its overall structure.
[0027] Example 1: A rock wool sandwich panel with a reinforced structure, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes an outer shell 1 and a rock wool board 2, with the rock wool board 2 disposed inside the outer shell 1. One side of the outer shell 1 is provided with a connector 3, and the other side is provided with a connector groove 4. The connector 3 includes a set of plug portions 301, two sets of ramp portions 302, and two sets of sealing grooves 303, arranged from left to right. The connector groove 4 includes a set of slot portions 401, two sets of elastic portions 402, and two sets of sealing strips 404. The plug portions 301 and slot portions 401 are adapted to each other, ensuring precise alignment during splicing and increasing the contact area through tight fitting, thereby improving the structural strength and sealing of the splice.
[0028] See figure Figure 1 , Figure 2 , Figure 4 and Figure 6 In the above embodiment, the elastic part 402 bends toward the slot part 401, and an elastic strip 403 is provided at the bend. This provides reasonable deformation space for the plug part 301 to be inserted to ensure smooth assembly, and the elastic strip 403 enhances the rebound force to ensure tightness when locked with the inclined part and improves the splicing stability.
[0029] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6In the above embodiments, both the elastic strip 403 and the sealing strip 404 are fixed to the elastic part 402 by adhesive bonding, ensuring that the elastic strip 403 maintains a locking effect during repeated deformation and the sealing strip 404 continues to perform a sealing function.
[0030] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In the above embodiments, the elastic strip 403 is made of natural rubber, and the sealing strip 404 is made of EPDM rubber. Natural rubber has excellent elasticity and resilience, which ensures that the elastic strip 403 provides stable elastic force during the compression-reset process, ensuring the locking effect. EPDM rubber has better weather resistance, aging resistance, and water resistance, allowing the sealing strip 404 to continuously perform its sealing function in long-term exposure environments, effectively preventing moisture penetration. The elastic strip 403 and the sealing groove 303 are compatible, and through precise fitting, the elastic strip 403 forms a tight filling in the sealing groove 303. It can also fully fit with the inner wall of the sealing groove 303 by utilizing the deformation characteristics of the elastic strip 403, enhancing the sealing pressure at the joint, further blocking the intrusion path of rainwater and moisture, and improving the overall sealing reliability.
[0031] See Figure 1 In the above embodiments, the outer shell 1 is made of galvanized steel sheet. The electrochemical protection of the galvanized layer enhances the corrosion resistance of the outer shell 1, effectively resisting environmental erosion such as moisture and rain, and extending its service life.
[0032] Example 2: To improve the strength of rock wool sandwich panels and make them less prone to deformation, Example 2 is an improvement on Example 1. (See attached document for details.) Figures 1-3 The interior of the outer shell 1 is fixed with multiple sets of reinforcing plates 5 by rivets 6, and the multiple sets of reinforcing plates 5 are evenly and equidistantly arranged. The purpose of fixing multiple sets of equally spaced reinforcing plates 5 inside the outer shell 1 with rivets 6 is to disperse external forces through a uniformly distributed support structure, avoid excessive local stress that could cause deformation of the outer shell 1, and at the same time enhance the overall structural rigidity and impact resistance of the sandwich panel. The reinforcing plates 5 are in the shape of an "I" and are made of polypropylene plastic material. The mechanical properties of the "I" structure are used to disperse stress and enhance bending resistance. The lightweight and chemical corrosion-resistant properties of polypropylene are also used to reduce the overall weight of the sandwich panel. As a non-metallic material with extremely low thermal conductivity, polypropylene can effectively block the heat transfer path between metal components, eliminate the thermal bridge effect, and further ensure the thermal insulation performance of the rock wool sandwich panel.
[0033] The implementation principle of this utility model is as follows: When assembling two sets of rock wool sandwich panels, the worker inserts the plug part 301 into the slot part 401 of the other set of rock wool sandwich panels. During the insertion process, the inclined part guides the elastic part 402 to produce controllable deformation, ensuring that the plug part 301 smoothly enters the slot part 401. The precise engagement of the plug part 301 and the slot part 401, compared with the hollow fit of the traditional male and female slots, increases the physical contact area of the splicing part, significantly enhancing the structural strength. Even when subjected to strong wind impact, mechanical vibration, or external force collision during installation, it can effectively resist deformation, completely making up for the defects of the traditional weak structure. When the plug part 301 is in place, the elastic part 402 quickly resets and tightly locks into one side of the inclined part, forming a firm automatic locking state. This locking method not only avoids the loosening problem that may occur in traditional splicing, but also greatly improves the stability of the assembly. At the same time, when the elastic part 402 resets, it will drive the sealing strip 404 to fit tightly into the sealing groove 303, playing a sealing role.
